'1 Claims.

Our invention relates to the class of hospital apparatus, and has for its object the cleanly evacuation and cleansing of the colon and voiding urine.

To this end, our invention consists generally of a receptor adapted to be held comfortably and closely against the patients body; a means of preventing splashing of the discharges against the body; adjustable means of fastening the receptor to the bed or other support of the patients body to maintain close contact of body and receptor; and other valuable inventions and discoveries, all of which are more particularly explained and described in connection with the description of the following drawings, in which:

Fig. 1 is a side view partially in section of the receptor.

Fig. 2 is a front view of the receptor.

Fig. 3 is a side view and partial longitudinal section of the conveyor.

Fig. 4 is a central vertical cross section of the bed type of conveyor.

Fig. 5 is a partial vertical section of the receptor and conveyor.

Fig. 6 is a vertical section on line AA Fig. 5 of the table type of conveyor.

Fig. 7 is a view of the assembled portable table apparatus.

Fig. 8 is a cross section of a contacting edge of a receptor made of flexible material as rubber.

In Figs. 1 and 2, No. l is the receptor shell, No. 2 is the handle of same. No. 3 is an inclined partition, necessary for the support of the male external genitalia during use, and to prevent splashing of same by discharged material, the opening 4 permitting escape of voided urine and passage of a tube to carry fluid for cleansing colon. That portion of the receptor which is applied to the body is shaped to fit same. The edge [3 of shelf 3 passes across the area of the transversus perinei muscles, affording support to the obstetrical perineum against bearing down pressure, and contamination by urine from above. A slope downward toward opening 4 of approximately 15 deg. has been found best. No. 5 is the thickened flat edges of receptor shell I, ending in a broad, forwardly extending ledge 6, being curved as shown to fit that part of the patients body. This is very necessary to afford a close contact. Of great importance is the elimination of splashing of the parts about the anus. This is accomplished by the interior lines of that part of receptor l lying below shelf 3, as shown. No. l is a supporting ledge which rests upon upper edge of conveyor as shown in Figs. 3, 4, 5 and 6 when in use. No. It] is the downward extension of receptor shell I, having two semicircular ports ll, l2 giving passage to the exit pipe 24 in Figs. 3 and 4. No. 14 is a locking pin projecting downward from the receptor l below the forwardly 5' extending ledge 6 to hold receptor tightly pressed against patient. No. 45 is a threaded boss in which screws a reducer 15 having in it a smooth passage I? for a small hose. Nos. l8 and I9 are elastic straps used to hold the receptor close to the patients body in the special bed type of apparatus.

In Figs. 3 and 4, the bed type conveyor has a shell 23 adapted to fit closely around the downward extension ll] of receptor shell in Figs. 1 and 2. No. 24 is the exit pipe adapted to be extended by a rubber hose, not shown. No. 25 is the bottom of the conveyor. A slope of approximately 15 deg. toward exit pipe is essential to prevent splashing and quickly convey discharges to hose. Conveyor and receptor move as one upon a flat surface.

In Figs. 5 and 6 the table type of conveyor is shown as fastened in the wooden table top 29- by screws 30 and 30 passing through vertical edge 28. No. 3! is the level rear portion of the bottom of the conveyor, and 32 is the forward, generally conical bottom of same, sloping to connect with the vertical exit pipe 33. No. 34 is a metal recess fastened in table top 29 a short 30 distance ahead of the conveyor and adapted to receive the pin IA of receptor in Fig. 1 when receptor is fitted closely against patients body and locked in position by pin l4 and buttons as 35 in Fig. '7.

In Fig. 7 the table type conveyor of Figs. 5 and 6 is shown as in place in portable type table top 29. In it sets the receptor of Fig. 1. No. 52 is the carrying case for all parts in Fig. '7, except table top 29, and serves as the support for the 40 head end of table top.

The receptor l as in Fig. 1 is shown as placed in position in the crotch of human body shown in Fig. 7.

In Fig. 8 the rubber edge I08 is shown as having an extending edge I26 which extends outward as at I21 when not in contact, but doubles back to position I26 when in contact with patients body I28.

The invention is designed primarily to assist in removing toxic, septic and infective waste from the body by facilitating physiologically complete evacuation of the bowel, at the same time permitting emptying of the urinary bladder. We are aware that there is apparatus used for this purpose, but all of it falls short of meeting the requirements of comfort and cleanliness important in hospital practice.

Accepting the theory that as much as two hours may elapse from the inception of evacuation until its completion, we must provide all means possible harmlessly to promote the act during the time necessary. If the patient is too ill to leave his room, or bed, the apparatus must be carried to him. In all its features it should contribute to the comfort of the patient, for it is a wellknown fact that every function is carried on more efiiciently when the one directly concerned is comfortable in body and mind.

While the use of a padded or upholstered surface for the patient to rest upon is common, the additional special contributions to comfort by the portable apparatus described herein is the principle and application of the leg supports which maintain the legs in the squatting posture, permit complete relaxation of same while free to move without restraint. This squatting, or natural, posture stimulates peristalsis, upon which we must rely for evacuation. Suction to empty colon is inefiicient, with the danger of drawing a portion of intestinal wall into apparatus used.

A further feature, shared by all conveyors described herein, is a comfortable close fit to the parts. The sense of pressure imparts such a feeling of assurance of cleanliness that the patient has no misgivings as to accidental soiling of person or linen, relaxation is complete, and discharge is unhindered. A feeling on the part of the patient of insecurity, of actual discomfort and of known uncleanliness has limited the usefulness of much of the available apparatus.

Cleanliness is our first line of defence against septic material. Fissures and abrasions about .the anal area are common. Any system of cleansing the colon which does not afford protection against splashing is a direct exposure to infection. Size and mobility of receptor make sterilization by boiling or other means very easy.

There are known in the art designs of discharging means for feces and urine, which are held in close contact with the patients body by attachment to belts or shoulder straps on the body. These arrangements are extremely annoying to nervous patients and interfere with necessary sleep. We show an elastic holding means for the receptor, fastened to the bed on which patient rests, which avoids annoying attachment to the patient.

We do not confine the meaning of the claims herewith or later submitted in this case to the particular designs shown in the accompanying drawings, but intend such claims to be broadly interpreted and to cover the use or application of the novel ideas herein explained and illustrated in any form or mechanical design that may be developed during the life of our patent rights.
